SPECIFIGATION forming part of Letters Patent No. 644,603, dated March 6,1900.

Application filed July 1 8 l 898.

To aZZ whom it may concern:

Be it known thatl, WILLIAM J. HUTCHINS, a citizen of the United States,residing at J oliet, in the county of Will and State of Illinois, haveinvented certain new and useful Improvements in Wire-Nail Machines, ofwhich the following is a specification, reference being had therein tothe accompanying drawings and references marked thereon.

This invention relates to improvements in that class of nail-makingmachines wherein the nails are formed of wire, and is designed as animprovement in the wire-nail machine patented by me April 6, 1897, No.580,318,

which. improvements are fully set forth and described in the followingspecification and pointed out in the annexed claims.

The objects of this invention are to produce a machine of greaterstrength and durability without materially increasing the generaloutline dimensions; to decrease the stroke of the parts employed informing the nail-heads, thereby increasing the power of compression anddecreasing the vibratory movement of the machine when in action; torender the machine capable of making either one or two nails at a singleoperation or revolution; to construct and confine the constituent partsof the machine so that there will be no perceptilole yield or unduestrain experienced during the operation thereof,thereby red ucin g theliability of breakage to a minimum and render ing it possible to fullymaintain adjustments of parts, resulting in a more nearly continuousoperation, and hence a greater production of nails; to increase theadjustments of the grip-dies, so as to make it possible to bring thenail-wire in more minute alinement with the heading-tool; to increase bya change of form the leverage of the grip or pinch lever, so as toreduce the wear thereofand the power required to operate it; to providea pinchfeed instead of the grip-feed heretofore em,- ployed, and otherobjects which are described hereinafter. a

Referring to the drawings, 1 is the machinebed, 2 2 the standards uponwhich the bed is mounted, and 3 an outer standard-bearing for supportingone extending end of the machine drive-shaft.

The bed has made integral therewith a pair of end boxes 4 and4 andopposite side boxes 5 6 and 5 6, each of which is provided with a capproperly secured into position by means of screws or studs.

7 is the drive-shaft, journaled in boxes 4 4 and 3, is made with acrank-head 8 between boxes 4 4, and has fixed thereon the mitergears 99, a crank-disk 10, a fly-wheel 11, a tight belt-pulley 12, and sleevedthereon a loose belt-pulley 13 in the manner shown in Fig. 1.

14 14 are opposite side shafts, respectively, journaled in boxes 5 6 and5 6, and have respectively fixed thereon miter-gears 15 (arranged,respectively, in mesh with and driven by gears 9 9) and eccentrics 16,and the shaft at the right side of the machine also has fixed thereonthe grip or pinch cam 17, which affixed parts are arranged as shown inFig. 1.

On the central portion of bed 1 is a longitudinal guideway formed by apair of opposite upright parts 18 18, and aflixed upon the forward endof said parts 18 18 is a pair of opposite posts 19 19,and swung frompins 20 20, respectively, of said posts is a pair of opposite links 2121.

22 is the header cross-head, made with sideextending trunnions 23, (seeFigs. 9 and 10,) which are hung in the depending portion of said links,and thereby support the forward end of said cross-head so it will swingat that end to bring the heading-tool 24 down to be in line with thenail-wire at the full forward movement of said head and raise said toolto be above the line of the nail-wire at the full rearward movement ofsaid head. The rear end of said cross-head is made to socket and couplewith a pitman 25, which is strapped to and driven by the crank of shaft7, which coupling is efiected by means of a link 26, held in a fork ofthe cross-head by a cross-pin 27 and adjustably held in a longitudinalbore of said pitman by means of a cross-key 28, (see Fig. 3,) and saidrear end of said crosshead is guided by means of a pair of oppositesliding blocks 29, arranged in ways in the rear portion of saidlongitudinal guideway, (see Figs. 1, 3, and 10,) and have respectivelyarranged therein the end portions of said coupling-pin 27 and arerespectively confined against lifting by means of the oppositeguideplates 30 30. In line with said longitudinal guideway at theforward end of the machinebed is an upright anvil portion 31, made witha vertical recess in its side facing said guideway, which recess mergesinto an opening through the bed, which opening extends across the spacebetween said anvil and guideway and a distance back below said guideway.Arranged adjacent the inner side of said anvil is thedie-block-supporting table 32, with its depending portions extendingdown into said opening, and turned up through a screwthreaded hole in aledge in the lower portion of the bed is a screw 33, which engages saidtable, as shown in Figs. 3, 10, and 13, for the purpose of givingvertical adjustment to said table. 34 is the die-block placed upon saidtable, with its depending cross portion fitted into a correspondingrecess in said table, (see Figs. 13, 14, and 1G,) and is made with arear extending portion fitted into the recess of anvil 31, is recessedin its face to form a seat for the grip-dies and for a gib 35 foroperatively confining the operative die, is provided with a hardenedbattering-block 36, set therein in a position to be in rear of theworking end of the grip-dies, is further provided with abarrel 37 inline with and in rear of the dieseat and with threaded holes for theplacing of set-screws for holding, confining, and adjusting thegrip-dies, and is held seated upon said table by means ofclamping-blocks 96, which are secured down by means of studs set inanvil 31.

Across the machine-bed either way from the space between thelongitudinal guideway and said die-block is a guideway, that at theright consisting of an adjustable guide-box 38, wherein one cutter-head39 is placed, and that at the left consisting, at one side, of anupright portion 40 of the bed and an adjustable gib 41 at the oppositeside of a plate 42, attached at one end to an upright lug 43 of the bedand resting against table 32 at its op posite end in a corner recess ofsaid table, (see Fig. 16,) thus spanning the space at the side of thegrip or pinch lever of the machine, and at the top of a covering-plate44, wherein the opposite cutter-head 45 is placed. Said cutter-heads arerespectively operated to simultaneously move toward and from each otherby means of the opposite eccentrics 1G 16 through the agency of therespective pitmen 46 46, which pitmen are socketed in the end of saidheads and coupled therewith by means of pins, such as shown in Fig. 8,and have attached to their facing end portion by means of screws, suchas shown at 47 in Fig. 6, clamps 48 49, which clamp and hold thepoint-cutters 50 at one side of their head. (See Figs. 1, 4, 5 and 6.)

The screws 47 are placed in verticallythreaded holes of their respectiveheads, and by turning them the lower clamps 49 will be adjustedvertically to correspondingly adjust the point-cutters, and when thusadjusted the nuts turned on the upper portions of said screws are setdown hard upon the upper clamps 48, thus firmly pinching and holding thepoint-cutters. The rear end of said cutter-heads are stepped or offset,as shown in Figs. 5 and '7, and entered at said respective olTsets arescrews 51 and 52, which extend longitudinally through the head andengage the rear end of the respective cutters 50, as shown in said Fig.5, for the purpose of adjusting said cutters, and turned into the headare set-screws 53 54, which engage against said adj listing-screws,respectively, to lock their engagement.

The cutters 50 of the opposite heads 39 45 may be adjusted vertically bymeans of the screws 47 and clamps t8 49, so as to properly register onthe wire lines. Also cutter-head 39 may be adjusted laterally or in thedirection of the wire line to bring the cutters to register laterally bymoving the guide-box 38, which is done by means of the shouldered screw55, which is threaded into said box and retained by being placed in thefork of an upright lug of the bed, as shown in Fig. 1.

In the vertical recess of anvil 31' in the rear end of the die-block isplaced a wedge 56, made adjustable by means of a shouldered screw 57, asshown, for the purpose of adj usting the die-block toward or from thepath of the pointcutters to regulate the distance between the face ofthe grip-dies and pointcutters, and thereby regulate the stock orquantity of wire to be left projecting from the grip-dies after thenails have been cut from the nail-wire, hence gaging the quantity ofwire from which the nail-heads are formed to govern their size. Iheheader cross-head 22 is also provided with a wedge 58, arranged in aVertical recess in rear of the heading-tool 24:, made adjustable bymeans of a shouldered screw 59, as shown, for the purpose of adj ustingsaid headingtool to gage its stroke in forming the nail-heads.

The grip-dies (shown at and 61 in Fig. 13) are placed in their seat indie-block 34, as represented in said figure, with the die 60 held in afixed position and the die 61 operatively confined, so as to beyieldingly held open from die 60 by a means not necessary to be hereindescribed and pinched to grip the nailwire between it and die 60 bymeans of the action of the pinch or grip lever, as hereinafterdescribed.

Adjacent the left side of anvil 31 the bed is recessed vertically, asshown at 62 in Figs. 1 and 13. Across said recess is placed a pin 63 andupon said pin is fulcrumed the griplever 64, as shown in said figures.The upper end portion of said lever is provided with a pinch-screw 65,adj ustably arranged to engage against the end of die 61, and the lowerportion of said lever extends down through said bed-recess across underthe bed to the opposite or right side of the machine and terminates withan affixed forked bearing 66 under grip-cam 17 of shaft 14, wherein isplaced a roll 67, with its trunnions resting in the bearings of saidfork and its face contacting said grip-cam, the action of the camagainst said roll causing the lever to be actuated at stated regularintervals to pinch said grip-die 61, and as a means of yieldinglyholding said roll 67 in constant contact with cam 17 and releasing thepinch on said die when the position of said cam so permits a coil-spring68 is arranged under said lever at its end below said roll, which springis stepped and thus supported in a barrelbracket 69, which is attachedtoone of the machine-standards, as represented in Fig. 2. The position oflever 64 is-such as to be in line Vertically with the die-block, andhence in line with the table-adjusting screw 33, and as a means ofgiving access to the socket of said screw by means of a suitable wrencha hole 7 O, as shown in Fig. 19, is made through "said lever directlyunder said screw.

The machine employing a crank-feed is therefore of that class known as atwo-partmovement machine, one-half revolution being consumed in feedingforward the nailwire, leaving the remaining one-half revolution topoint, shed, and head the next succeeding nails. Therefore the grip-cam17 must be so shaped as to accommodate the several consecutive movementsof each revolution of the machine. By reference to Fig. 18 line C Cdenotes the cross-center of the cam, the part below said li'nerepresenting the time of the machine when the nail-wire is being fedforward. Therefore said cam is reduced at that portion so as to permitthe grip-dies to be open and free during that period of time of theaction of the machine, and the part above said line represents the timeof the machine when the feed-head is receding and the nails are beinggripped, pointed, shed, and headed.

The section of the cam from D to E represents the time the die 61 isbeing pinched to grip the nail-wire, the section from E to F the timethe nails are being pointed and shed from the machine, the section fromF to G the time the nail-heads are being formed, and the section from Gto H the time the pinchis being released on die 61, so it may open topermit a succeeding feed to be made. That section of the cam from I to Fis made inclined, as represented, for the purpose of graduallyincreasing the force of pinch on die 61, so that the maximum force ofpinch will be exerted on said die during the time of heading the nailsand only during said periods of time.

Attached to the front end of bed 1 is a frame 71, which supports at itsouter end a set of wire-straightening rolls 72 and guides 73, which aremade adjustable in the usual manner and openable so the nail-wire may belaid therein and then closed upon the wire. The inner end portion ofsaid frame comprises a guideway 74, one side of which is made adjustableby means of set-screws, as shown. Placed upon and within said guidewayis the feed-head 75, adapted to slide upon said way in the direction ofthe machine wire line. Fixed upon said head at one side of the wire lineis a circular block 76. Opposite said block is arranged in a suitablehousing an adjustable square block 77, made adj ustable by means of aset-screw turned against its outer side and made with its side facingblock 76 beveled, as represented. Placed against said beveled block 77is a verticallyarranged roll 78, yieldingly held into position by meansof a spring 79.

The nail-wire is placed between the block 76 and roll 78, and at eachforward movement of said head the roll will wedge back between the wireand beveled end of block 77 sufiicient to pinch the wire firmly againstblock 76, and thus hold it to cause the proper feed to be made. As saidhead recedes the action of the wire against roll 78 causes said roll tomove back the bevel of block 77, and this releases the pinch, so thewire may remain stationary until a succeeding feed is made.

Bed 1 is made with a forward-extending arm 80, which has fixed thereinan upright pin 81, whereon is fulcrumed the feed-lever 82, which extendsat one end to engage with and operate the feed-head, and has sleeved onits opposite end the hub of a knuckle 83, which connects with a secondknuckle 84 through the medium of a connecting-rod 95, as shown, and saidlatter knuckle is sleeved on a crankpin 85 of disk 10, which crank,comprising said disk and pin, drives said rod to operate said lever. Pin85 is made adjustable in a face-slot of disk 10 for the purpose ofchanging the stroke of said crank to regulate the movement of thefeed-head, so that various lengths of feed may be made to producevarious lengths of nails.

Grip-lever 64 is provided near its outer end with a vertical plainsurface 86, and attached to the under side of bed 1, adjacent saidsurface, is a depending bracket 87, set so as to be engaged by and forma guide at one side of said lever to prevent side movement thereof atthat end. (See Fig. 2.) Also said lever is made with recess 88 in itsside immediately above its point of fulcrum for the purpose of providingspace for the guideway sideplate 4:2, in order that the head and hub ofsaid lever may be brought more directly in line with the grip-dies.

In the construction of eccentrics 16 the one at the right of the machineis made of broader face than the strap of the pitman placed thereon,(see Figs. 1 and 2,) so that said strap may have a limited slidingmovement on said eccentric to accommodate different positions ofcutter-head 39 when adjusted by moving box 38, as stated.

In operation the feed mechanism is operated to intermittently feedforward sections of nailwire of length suitable from which to form thesize of nails being made. At each forward movement of the feed thegrip-cam is turned to such position as to permit the griplever torelease its pinch on the grip-die 01, thus permitting the dies to beopen during such feed movement at the same time the header cross-head isreceding, causing its tool 24 to swing rearward and upward, so as to beabove the path of the headed ends of the infed nail-wire. At theconclusion of such feed the grip-cam has turned so as to act upon thegrip-lever to cause it to pinch die 61, and thus grip the infed wire tohold it during the period of time the feed-head is receding, duringwhich time the point-cutters advance upon the nail-wire adjacent theface of the gripdies and point the nails, severing them from thenail-wire, and leaving a short section of the wire projecting from thegrip-dies from which to form the nail-heads, which at the receding ofthe point-cutters is immediately engaged by the heading-tool and theheads formed.

During the forward or advancing movement of the header-tool it is by theswinging movement of its head brought down to line with the nail-wireand during its descent engages and sheds the nails from the nail-wire,permitting them to fall through the opening in the machine-bed into asuitable receptacle placed under the machine.

In constructing the machine the wire passage-way through the die-blockand bed-anvil is made elongated vertically, so as to accommodate thefeeding of two wires, one a little distance above the other; also, toaccommodate two wires the grip-dies are made doubleseated, as shown inFig. 23, the point-cutters are made double, as shown in Fig. 25, and thestraightener rolls are made with an extra groove either way from theircentral groove, as shown in Fig. 22; also, when the machine is inservice, making two nails at a single revolution, the elongated facedheading-tool, such as shown in Fig. 27, is employed, which covers bothwire ends, as represented in Fig. 10. lVhen making one nail at eachsingle revolution of the machine, the header-tool, as represented inFig. 28, the grip-dies, as represented in Fig. 24a, and thepoint-cutters, as represented in Fig. 2b, are employed in place of theones described for double service.

The action of the machine and the feed is the same in single or doubleserviceviz., making one or two nails at a single revolutionand themachine maybe changed to either service by changing the header tool, thepoint-cutters, and the grip-dies and employing the central groove of thestraightenerrolls for single-nail making and the two adjacent groovesfor double-nail making.
